I needed to write this someday.
Some people say silver and gold are better for (blah blah), citing better conductivity as the reason.
Reality check time.
Silver's conductivity is 5-10% higher than copper.
But when people buy pure silver cables they buy thinner because 1) it is more expensive and 2) the higher conductivity makes up for the thinner gauge.
Right?
Wrong.
The difference in area between wires 1AWG different in gauge is roughly 26%.
So for the same amount of money, you can get thicker copper cable which is more conductive.
Next, gold.
Gold is less conductive than copper.
End of discussion.
